My keyboard is currently double adding ‘b’ when I click on the B key. Very annoying and leads to variable name bugs when I don’t catch it. I just received my MacBook Pro back from service 2 weeks ago (I had popping/cracking noises coming from the hinge / case when opening the computer or when heating up or down). I don’t remember this B issue happening before :(
